Product description
Thin film lithium niobate phase modulator is a high-performance electro-optic conversion device, which is independently developed by our company and has complete independent intellectual property rights. The product is packaged by high-precision coupling process technology to achieve ultra-high electro-optical conversion efficiency. Compare with that traditional lithium niobate modulator, the product has the characteristics of low half-wave voltage, high stability and small device size, and can be widely apply to the fields of digital optical communication, microwave photonics, backbone communication networks, communication scientific research projects and the like.
